Description

Frame unit and table

Technical Field

The present invention relates to a frame unit for simply and firmly joining a frame of a table and a table to which the frame unit is applied.

Background

Generally, a corner portion of a desk, table, cabinet, shelf, or the like includes a portion in which ends of three pillars (i.e., two horizontal pillars and one vertical pillar) constituting a right angle with each other are in contact with each other.

The method for combining the three struts comprises the following steps: method of connecting pins using nails or the like, method of assembling by forming joining projections and grooves at joining portions, method of welding joining in the case of metal posts, method of connecting pins using nails or the like, method of welding joining by forming joining projections and grooves at joining portions, method of welding joining by using metal posts, method of connecting pins using nails or the likeA separate stent approach, etc. The method of assembling the corner portions using the bracket and the fastening screws has a characteristic of easily disassembling and assembling the respective parts compared to other methods, and thus the bracket fixing method is recently being widely used. That is, the two members are adhered to each other at the corner portions of the two members which are in a perpendicular contact state

The bracket of the shape is then fastened to the bracket with fastening screws, and thus coupling between the corner portions and the pillar members of the corner portions is accomplished.

For example, as shown in fig. 12, horizontal support members 110 are disposed at corners of a bottom surface of an upper furniture plate 100, the horizontal support members 110 are disposed at a predetermined distance and cross each other at right angles, brackets 150 are disposed between the horizontal support members 110, fastening members 140 such as bolts provided at column members 120 are protruded through holes of the brackets 150, and nuts are fastened to the fastening members 140 to couple the column members 120 and the horizontal support members 110 to each other.

However, the above-mentioned conventional furniture assembly structure is provided with a bracket for coupling the column member and the horizontal support member, and thus It is not only inconvenient to disassemble and assemble the furniture, but also has a problem in that It is difficult to apply the structure to a diy (do It yourself) product which can be directly assembled or disassembled by a user.

In addition, the conventional furniture assembly structure has the following problems: the bracket is formed of a plate-shaped metal body, so that the bracket may be deformed, and the column part and the bracket may not be firmly coupled only by the coupling of the fastening tool to each other, so that the shaking of the column part occurs to affect the stability of the furniture.

The prior art relating to the assembly of such furniture is numerous, some of which are as follows:

patent document 1 relates to an improvement of a corner post assembly structure of furniture, and includes a corner portion formed by mutually joining three posts of a cabinet, a shelf, a desk, a dining table, various tables, and the like at right angles; more specifically, a corner post assembly structure of furniture and use thereof are describedThe support for assembling a strut uses a support having a coupling pin on one surface and a nut hole formed on the other surface

And a shape that allows easy and firm assembly and disassembly between the corner posts.

Patent document 2 describes a joint for assembling furniture which is crossed at right angles, a bolt is screwed into the inside of the furniture which is crossed at right angles, then the inside of the furniture which is crossed at right angles is entered, and then a fixing pin for preventing the bolt from being detached is combined in a direction which is crossed at right angles with the entered bolt so as not to expose the outside.

Patent document 3 describes a right-angle panel assembly structure of an assembly type wood furniture, in which a male panel is firmly assembled to a female panel when rectangular panels are assembled so as to be perpendicular to each other, and the panels are not shaken or separated after the assembly.

In the above-described conventional technique, since the bracket or the like is first coupled to the upper plate, a portion protruding from the upper plate collides with the bracket when the upper plate is stored and moved, and the upper plate is damaged. To solve this problem, there is a disadvantage that it is very troublesome and time-consuming to assemble all the parts on site.

Detailed Description

Preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings, and descriptions of known technical parts are omitted or simply made to make the description simpler.

As shown in fig. 1 to 5, a frame unit 1 of an embodiment of the present invention includes: vertical frame 11, first block 12, connecting frame 13, second block 14 and joining tool 15. Here, a reinforcing frame 16 may be further included.

The vertical frame 11 is formed in a substantially rectangular pipe shape, and is opened at an upper side thereof and is formed at a side thereof with a coupling opening 111 opened substantially in a "U" shape.

In addition, there are four vertical frames 11, and the vertical frames 11 support thick plates 21 to be described later from the ground.

The first block 12 is inserted into the upper end of the vertical frame 11, and is coupled to a second block 14 and a connection frame 13 to be described later, to form a substantially rectangular parallelepiped, and is formed with a quadrangular coupling groove 121 having an upper surface and a side surface opened.

The first block 12 has a guide groove 122 formed on the inner surface of the coupling groove 121 to correspond to the guide 142 of the second block 14, and the guide groove 122 is formed to be deeper than the coupling groove 121 and to expand outward. Here, the guide groove 122 is formed in a shape of a truncated V on a side surface, and a wedge shape with an opened upper portion is formed in a front surface provided with the first inclined surface 122 a. At this time, the vertical surface of the guide groove 122 is spaced from the coupling groove 121, and the first inclined surface 122a is connected to the coupling groove 121. In this regard, a detailed description will be made hereinafter.

In addition, the first block 12 is formed with a substantially U-shaped anti-intrusion projection 123 projecting outward around the side opening of the coupling groove 121. Accordingly, when the first block 12 is inserted into the upper end of the vertical frame 11, the protrusion 123 is inserted into the coupling opening 111, the lower end of the protrusion 123 is caught by the coupling opening 111, and the first block 12 is prevented from being excessively inserted into the vertical frame 11. At this time, the first block 12 is interference-fitted and fixed to the vertical frame 11.

In addition, the first block 12 may further have a frame portion 124 extending outward around the protrusion 123. Accordingly, when the first block 12 is inserted into the vertical frame 11, the frame part 124 covers the corner of the coupling opening 111. That is, the bezel part 124 may prevent the sharp corner portion of the junction port 111 from being exposed to the outside. Therefore, the human body is prevented from contacting the sharp corner portion of the junction 111, and the human body is prevented from being injured.

The connecting frames 13 connect the vertical frames 11 to each other in the left-right direction, and are disposed respectively in front of and behind the vertical frames 11.

The connection frame 13 is formed in a substantially rectangular pipe shape, is coupled to a second block 14 to be described later, and is inserted into the coupling groove 121 of the first block 12.

In this regard, a detailed description will be made hereinafter.

The second blocks 14 are inserted into both ends of the connection frame 13 and into the first block 12 to serve as a medium body connected to the vertical frame 11.

Further, the second block 14 is provided with a block 141 and a guide 142, the block 141 is substantially a rectangular parallelepiped, and the guide 142 has a second inclined surface 142a on a side surface of the block 141 corresponding to the guide groove 122. At this time, the guide 142 is formed to expand outward from the periphery of the block 141.

In addition, the second block 14 is projected between the block 141 and the guide 142 to form a correction projection 143 corresponding to the circumference of the connection frame 13. Accordingly, when the block 141 of the second block 14 is inserted into the connecting frame 13, the end of the connecting frame 13 is closely attached to the alignment protrusion 143, and the second block 14 is prevented from being inclined or shaken from the connecting frame 13.

In the second block 14, a through hole 141a is formed in the block 141 so as to extend from the upper end to the lower end, and a coupling bolt 152 to be described later is inserted into the through hole 141a so that the upper end of the through hole 141a is enlarged.

Accordingly, when the second block 14 is inserted into the coupling groove 121 of the first block 12 in a state where the block 141 of the second block 14 is inserted into the connection frame 13, the guide 142 of the second block 14 is inserted into the guide groove 122 of the first block 12. That is, since the guide 142 of the second block 14 is inserted into the guide groove 122 of the first block 12, the second block 14 can be prevented from being separated in the lateral direction from the first block 12. Further, the second inclined surface 142a of the second block 14 is closely attached to the first inclined surface 122a of the first block 12, and the second block 14 generates a force pulling the first block 12 in an inward direction, thereby preventing the lower end of the vertical frame 11 from moving inward. Thus, the tables 2 and 2' can be supported firmly on the ground.

The joining tool 15 joins and fixes the first block 12, the second block 14, and the connecting frame 13, and includes an insert nut 151 and a joining bolt 152.

The insert nut 151 is inserted and fixed to a lower portion of the first block 12 and coupled with the coupling groove 121.

The coupling bolt 152 is screw-coupled with the insert nut 151. That is, the second block 14 is inserted into the first block 12 in a state where the second block 14 and the connection frame 13 are coupled, then the lower end of the coupling bolt 152 is inserted into the through hole 141a through the connection frame 13, and then the coupling nut 151 is coupled to the connection frame 13 through which the coupling bolt is inserted again. At this time, the head of the coupling bolt 152 enters the upper end of the through hole 141a of the second block 14, and the head of the coupling bolt 152 does not protrude outside the connection frame 13. Accordingly, the first block 12, the second block 14 and the connection frame 13 can be quickly and firmly coupled by one coupling bolt 152. Accordingly, the vertical frame 11 can be prevented from being bent or shaken right and left.

The reinforcing frame 16 is formed in a substantially rectangular pipe shape by connecting the vertical frames 11 to each other in the front-rear direction, is disposed at both upper sides of the vertical frame 11, and is welded and fixed at both ends to the vertical frame 11. Accordingly, the vertical frame 11 can be prevented from being bent or shaken in the front-rear direction.

On the other hand, as shown in fig. 1 to 11, the tables 2 and 2' according to the embodiment of the present invention include a frame unit 1 and a slab 21. Here, spacers 22, 22 ', 22 ″, a back plate 23 and fixing means 24, 24' may be further included.

The frame unit 1 supports the thick plate 21, and corresponds to the frame unit 1 described above, and therefore, detailed description thereof is omitted.

The thick plate 21 is formed into a substantially rectangular plate shape and is disposed above the frame unit 1. At this time, the thick plate 21 may be screw-coupled with the connection frame 13 and the reinforcement frame 16. That is, a plurality of screws are inserted through the lower portions of the connecting frame 13 and the reinforcing frame 16 to be coupled to the thick plate 21. Accordingly, the connecting frame 13 and the reinforcing frame 16 are firmly coupled to the thick plate 21, and thus, the first block 12 is prevented from being separated from the vertical frame 11. In more detail, the first and

second blocks

12 and 14 and the connection frame 13 may be integrally separated from the vertical frame 11 due to an external impact. However, if the vertical frame 11 and the reinforcement frame 16 are screw-coupled with the reinforcement frame 16 and the thick plate 21 in a state of being welded to each other, even if an external impact is applied, the thick plate 21 receives the first block 12, so that the first block 12 can be prevented from being detached from the vertical frame 11.

The spacer 22 is formed in a substantially circular shape with the thick plate 21 spaced apart from the frame unit 1 by a predetermined distance, and has a through hole 221 formed at the center thereof and at least one coupling member 222 coupled to the thick plate 21 formed at the periphery thereof, and the upper end of the through hole 221 is formed by being bored.

The spacer 22 is disposed between the frame unit 1 and the thick plate 21, more specifically, on the upper portion of the connecting frame 13, and the spacer 22 is fixed to the frame unit 1 by inserting the coupling bolt 152 into the through hole 221 of the spacer 22, then coupling the coupling bolt 152 and the insertion nut 151.

Here, the coupling member 222 improves the coupling force between the spacer 22 and the thick plate 21, and is symmetrically arranged or arranged in a "Y" shape with respect to the plane of the spacers 22', 22 "to prevent the thick plate 21 and the spacer 22 from being opened. That is, in some cases, the partition 22 ″ having 3 coupling members 222 formed therein is disposed at the corner of the table 2 ', and the partition 22' having two coupling members 222 formed therein is disposed at least at one of the connecting frame 13 and the reinforcing frame 16, but it is also possible to dispose the partition 22 'having 2 coupling members 222 formed therein such that the coupling members 222 are diagonally oriented on the table 2'.

Accordingly, a space is formed between the thick plate 21 and the frame unit 1, and a telephone line, an electric wire, or the like can be easily taken out from the table 2'. Furthermore, the patch panel or the plurality of wires can be fixed to the connection frame 13 or the reinforcement frame 16, so that the wires can be neatly arranged.

The back plate 23 eliminates interference between the tables 2, 2 'facing each other and the user, and serves to further reinforce the vertical frame 11, substantially forms a plate shape of a rectangular quadrangle, and is disposed behind the tables 2, 2' to be fixed to the vertical frame 11.

The fixing tool 24' serves to prevent the first block 12 from being separated from the vertical frame 11 due to external impact, and firmly fixes the first block 12 and the vertical frame 11 at the side of the vertical frame 11 using screws after the first block 12 is inserted into the vertical frame 11, thereby preventing the first block 12 from being separated from the vertical frame 11.

On the other hand, the fixing tool 24 may form a clip 241, and the clip 241 is formed by cutting a region of the side surface of the vertical frame 11 to bend the cut portion inward and upward. Then, a catching groove 242 corresponding to the catching piece 241 of the vertical frame 11 may be formed at a side of the first block 12. Accordingly, when the first block 12 is inserted into the vertical frame 11, the hook 241 is inserted into the engaging groove 242, and the first block 12 is prevented from being detached from the vertical frame 11.

The securing means 24, 24' described above may also be used in one or both applications, and the same manner may also be applied multiple times.

On the other hand, in the case where the spacer 22 is applied to the table 2', the connecting frame 13 and the second block 14 arranged at the front may be omitted to prevent the legs of the worker or the armrests of the chair from being caught, thereby preventing the thick plate 21 from being raised.

Accordingly, the present invention can assemble or disassemble the frame quickly and simply, and can easily install and arrange wires, etc. by using the spacer, thereby preventing the distortion of the vertical frame for supporting the table. Further, since the parts of the frame unit can be easily stacked, more frame units can be stored than the housing space, and the movement is easy.

In the description of the present invention, the same reference numerals are used for the same components even if the embodiments thereof are abnormal, and the description thereof may be omitted as necessary.

As described above, the present invention can be specifically explained by the embodiments with reference to the drawings, but the above-described embodiments are merely illustrations of preferred embodiments of the present invention, and thus it should not be construed that the present invention is limited to the above-described embodiments. Accordingly, in addition to the above description, a person skilled in the art to which the present invention pertains can easily carry out the present invention in the above-described embodiments and other forms within the same scope or can carry out the present invention within the same scope as the present invention only by describing the embodiments of the present invention.
